Zusammenfassung:We present new near-infrared observations of Sakurai's Object obtainedduring 1998-99 when this final helium shell flash object was in the dustcondensation phase. The infrared colours have reddened compared to earlierepochs, indicating increased dust condensation. The infrared spectrareveal all the features of a carbon star superposed on a dust continuum.[PUBLICATION ABSTRACT]
